My Data Security(ssakdook) is an application that protects your mail and messages. It can protect your data from leaking even after you share them.

This product has the function to encrypt the data you input (documents, memos, address book, etc.) as well as the sharable data (messages, e-mails, etc.).

If your friends have this app installed, the person whom you are sharing the data can receive the password from you and decrypt the data.

You can use the basic function without registering e-mail.

However, if you register your mail, you can block the decryption of encrypted data (character or texts).

The main feature of this app is that it has a function to block the data decryption even if the password is delivered to the other person.

You will need your email account to do this.

Email account registration is used for operational purposes, such as when retrieving login passwords and is never released to the public.
